, The present invention relates to a method-and apparatus forproducingcigars 'of a type tent, as the operator or operators must havesumcient time for serving the machine in a satisfactory manner.

According tothis invention the output is increased in a very simple way,so that the machine is able to produce the double number of cigars in acertain time or still more withoutrequiring more service andlwithoutincreasing the velocity of the machine working according to hithertoknown methods. Even if themachine according to the invention works witha less velocity than hitherto known machines, it is possible to obtain agreater output, and in such case the advantage is attained that thewearing out of the machine is decreased.

A preferred embodiment of a machine adapted for executing theprocessaccording to the invention is shown in the accompanying drawings.

.Beside the cigar machine proper a bunch producing device I ispositioned, .The cigar machine is provided with a buncher consisting oftwo r-' tatable drums 2 and 3 provided at their periphery with moulds 3which latter have the same shape as the bunches. An arm 4 is secured toa rotative shaft 5 journaled in the machine frame l2. A toothed segment34 is keyed to the shaft 5 and meshes with another toothed segment 35 ona bell-crank lever 36 pivoted to a pin 31. The free end of thebell-crank lever has a roller 38 which runsin a curved groove 39 in acam 40 which is keyed to a rotatable drive shaft 4|, the latter beingdriven in any convenient manner from a drive source, thereby impartingreciprocating swinging movements to the arm 4.

Another vertical shaft I9 is also rotatably journaled in the frame I 2and carries an arm 9. A toothed segment 42 is keyed to the shaft l9 andmeshes with another toothed segment 43 on a bell-crank lever 44 pivotedto a pin 45. The free end of the bell-crank lever has a roller 46 whichruns in a curved groove 41 in a cam 48 which is keyed to the shaft 4|which thus imparts reciprocating swinging movements to the arm 9.

' The arms 4 and 9 respectively are provided with retaining holdershavingpinchers 20 pivoted to plates 2| on the arms and forced togetherby springs 23. Each pincher- 20 has an upper projecting lug 49. arm 9are provided each with a thin slot 22 permitting theengagement of acutter blade l0 on the frame l2. a The machine is also provided withadevice for cutting off the clippings from the wrapped cigar, saiddevice'comprising scissor-blades and 8 arranged on the path of theswinging arm 9,and actuated in any well-known manner, for instance bymeans of a pin 50 engaging slots 5| in-the blades 1 and 8 respectively.The blades are fulcrumed at 52 and a rod 53 carries the pin 50. Verticalreciprocating movements are imparted to the rod 53 in any manner wellknown. in the art and therefore description thereof is not neededherein. For cutting the wrapper a cutting device such as adie'sh'ell29is provided on the frame l2. A leaf carrier 30 is providedon a swinging arm 3| which is carried by a vertical'shait 32 which isalso rotatably journaled in the frame I 2 and carries a toothed segment54 meshing with another toothed segment 55 on a doublearmed lever 56fulcrumed at 51 and having a roller 58 on its free end which engages acurved groove 59 in a cam 60 keyed tothe shaft 4|. Thereby reciprocatingswinging movementsare imparted to the arm 3| on the continuous rotarymovement of the shaft 4|. A cigar-wrapping device 6 is provided'having acluster developed and driven in any manner well known in the art andtherefore needing no description herein. Finally a container is providedin the frame for receiving from the holders cigars which have passed thecutting devices. Shoulders 6| are p0 sitioned above the drum 3, thewrapping mechanism 6' and the container H in such manner that they;engage the lugs 2| of the pinchers '20 as the arms 4 and 9 respectivelyare swung into a position above the stations mentioned, whereby thepinchers are opened and closed'respec- The pinchers of the tively fordelivering or gripping a bunch or cigar.

In operating the machine above described, a bunch [4 produced in thedevice I is inserted in a mould I3 in the drum 2 and. transferred fromsaid drum to the other drum 3 in known manner. Then the pinchers of thearm 4fetch thebunch from the drum 3 and transfer it to the rollingdevice 6 where it is provided with a wrapper. As

according to an embodiment of the invention abunch adapted for twocigars, each end'oi which forms the tip of one cigar, is treated, thedimensions and the shape of the bunch producing device, the buncher andthe-rolling deviceare ac commodated to the purpose.

Before the wrapping of the bunch a tobacco leaf is applied on thedie-shell 29. where a wrapper, the shape and dimensions of which areaccommodated to that of the bunch, is cut out and the wrapper is caughtby the leaf carrier 30', both processes being carried out in well knownmanner. It is well known that in order to .ensure proper wrapping, thewrapper must be flexible and moist. The wrapper is transferred from thedie-shell to the rolling device 6 byswinging the shaft. 3.2 with the arm31. During this transferring movement the leaf carrier passes apastecontainer 33, where as well the one end [8 of the wrapper 16 as themiddle portion I! of the same is provided with paste. The hatchetsurfaces in Fig. 2 show how. the paste is applied on the wrapper. Pasteis applied on the middle portion of the'wrapper. sothat at both sides ofthe out after dividingthe wrapped bunch, the wrapper is firmly fixed tothe bunch .duringthe cutting although the bunch has got out of shape.

After having been wrapped the cigar-body is immediately caught by thepinchers 20, whereafter the arm 9 swings in the direction of the arrowagainstv the cutters i and 8, which out off clippings at bothends of thecigar. On the eontinued swinging movement-of the arm 9 in the directionof the arrow, the wrapped bunch is divided by the knife, 1.!) at thespace 22 between the pinchers 20. This cutting operation should beperformed while the wrapper is still moist in order. to avoid tearing ofthe wrapper. T-wo finished cigars are thus obtained.

The cigars cutoff. remainin the pinchers 20, after having passed theknife I!) until they reach the container, H during, the swingingmovement of the arm ,9 and. are deliveredinto said container.

Since the slot 22 of the pinchers 20 is very small asufiicient supportis obtained for the cigars during the'dividing operation and the cutsurfaces will be smooth and a scratchingof the tobacco is avoided.

Instead of a fixed knife ID as shown in Fig. 1 it is of course possibleto use a rotatable blade.

'S aid knife l may of course be applied anywhere on thetravelling pathof the cigar-body l between the-rolling device 6 and the container H eg. at the scissor-blades I, 8.

Thecigar-body may also be at rest during dividingoperation.

:A device adapted for executing the process last mentioned is shown inFigs. 4 and 5.-

The holder consists of two elements 24, 25, pro vided with longitudinalgrooves and separated the from each other by a thin space 26. In frontof said space a pair of scissors is arranged. The

elements '24, 25 may be turned over round a spindlez28. m

'Ihecigar-body is conveyed by the arml9 to the holder 24, 25, where itis divided by the scissor blades 21. Thereafter the holder turns overand delivers the finished cigars into the container H or to a descendingsurface leading to said container.

The device may also be arranged in the way that the cigar-bodies rolldown into the groove of the holder from the rolling device.

It is also possible to make a bunch corresponding to the total length ofmore than two cigars,

by rolling a single wrapper round this bunch and dividing the cigar-bodythus obtained into more than two cigars. I v

The number of cutting means It for dividing the cigar body as well asthe number of parts, separated by thin spaces, of which the holder ofthe cigar-body consists, then of course is accommodated to the purpose.
